Why Do Leaves Change Color?

Tonight on The Quiet Shift, a question from your walk home: why does a leaf that spent all summer green suddenly burn red and gold, just before it lets go? We slip beneath the green to find the colours hiding there all along, watch a tree read the length of the night like a calendar, and follow the great, quiet salvage by which a forest saves its summer away. Why does the tree paint some leaves red at the very end, at real cost, for reasons scientists are still gently arguing about? And where does the green actually go when it is gone? Settle in, get comfortable, and drift off beneath the turning trees. New episodes of The Quiet Shift arrive each evening. Follow the show so tonight's story finds you.
